<p><span class="user-mention" data-user-id="116083">@pnkfelix</span> <span class="user-mention" data-user-id="116009">@nikomatsakis</span>  for the release this thursday, we ended up backporting a LLVM change as well to fully fix <a href="https://github.com/rust-lang/rust/issues/69225" target="_blank" title="https://github.com/rust-lang/rust/issues/69225">https://github.com/rust-lang/rust/issues/69225</a> - someone came up with a reproduction that the revert bugfix didn't work anymore. We never approved that in compiler meetings though, but I think we should approve this change. I'm not sure what process to follow here, but we do have artifacts both with and without the fix, and can release either technically</p>

<p>(nikic approved said LLVM change, and it's quite minimal -- <a href="https://github.com/rust-lang/llvm-project/compare/2cb41005ed5c4747b10d2bf01d8779d3bb4ae32d...7d5e7c023053660ffe494d72ce471e48ecc7f49b#diff-5a6e7b948274577e7852f0d53de949d0" target="_blank" title="https://github.com/rust-lang/llvm-project/compare/2cb41005ed5c4747b10d2bf01d8779d3bb4ae32d...7d5e7c023053660ffe494d72ce471e48ecc7f49b#diff-5a6e7b948274577e7852f0d53de949d0">https://github.com/rust-lang/llvm-project/compare/2cb41005ed5c4747b10d2bf01d8779d3bb4ae32d...7d5e7c023053660ffe494d72ce471e48ecc7f49b#diff-5a6e7b948274577e7852f0d53de949d0</a>)</p>

<p>yes, the default plan is to proceed with the LLVM backport commits</p>

<p>I'm fine with the LLVM backport commits, based on the discussion thread on <a href="https://github.com/rust-lang/rust/issues/69225" target="_blank" title="https://github.com/rust-lang/rust/issues/69225">#69225</a></p>
